Food grade gypsum (calcium sulfate - CaSO4), sometimes called "Burton Salts" is used by grain brewers to insure proper mash pH and improve extraction. Also used to simulate the highly gypseous water found in Burton-on-Trent, the birthplace of pale ales. Note that gypsum only lowers pH when mashed with grain.
